IMPROVED BOLT AND BNET-MACHINE.

The Schedule referred to in these Letten Patent and making part of the same.

I, JOHN MORGAN, Junior, of Wheeling, in the county of Ohio andvState of Vest Virginia, have invented a new and useful Improvement in, Bolt and Rivet-Machines, of which the following is a full, clear, and exact description, reference beingr had to the accompanying drawing forming part of this specification, and in which- Figure l represents a plan of a machine constructed in accordance with my improvement;

Figure 2, a sectional side view, taken as indicated by the line x x` in iig. 1; and

Figure 3, a front view of the machine.

Similar letters of reference indicate corresponding V parts.

My invention is designed as an improvement upon the machine secured to me by Letters Patent No. 64,896, bearing date May 21, 1867 and y The improvement consists in certain combinations and arrangements of parts, including a plunger having a double intermittent forward movement, to. form a bottom to a series of dies, and to eject the finished bolt or rivet.

Also, a revolving die-holder and retainer, operating to adjust and keep said holder steady for the proper performance of the work, l

1n the accompanying drawing- A represents the main frame of the machine, and

B, a main or driving-shaft, to which motion may be communicated in any suitable manner.

C is a countershaft, arranged at right angles to the driving-shaft, and deriving its motion therefrom by bevel-gear wheels D and The rod to be worked up into bolts or rivets, or, under a suitable construction ofthe dies and punches', it may be nuts, but it will suffice here to refer only to rivets, is fed, while in a heated state, over a suitably-grooved stationary knife, F,through each one in succession of a series of dies, a., arranged in an intermittently-revolving die-holder, G, as a die in it is brought and retained in position opposite the knife, during a pause in the movement of the die# holder.

H,is a gauge in the rear of thedie-holder, and which should be made adjustable, 'to regulate the length of rivet to be made.

The dies in the dic-holder are suitably 'recessed in their rear, to formthe head ofthe rivet.A

On the shaft b of the die-holder is a star-wheel, I,

against which a toe, J, ou` the shaft O works, once during each revolution of the shaft G, to give the necessary intermittent movement to the die-holder.

K is a. stop or retainer for the die-holder, said stop being in the form of a lever, pivoted asat c, and dropping into tapering notches d in the periphery of the die-holder, to adjust the latter to its precise position for the entry of the bar through it, and to hold the Y same steady, both din-ing such feed of the bar and in a subsequent pause, while the rivet-liead is being made onthe end of the rod.

This stop Kislifted, when it is required to give the die-holder `a forward rotary movement, by a cam, L on the shaft C, arranged to Work .witliin a yoke formed in the lever-stop K.

As the die-holder G moves the distance between the notches d d or dies a a at a time, the travel of the same past the stationary knife F cuts the length from oli' the rod, and the die-carrier G carries the blank` in the one die in line with va plunger, W, and header, M, at the Sametime bringing another die in the holder G opposite the knife F and gauge H, when the stoplever K again drops, to adjust and retain in position the die-holder G, so that, while a freshA feed `is being made of the rod, a rivet is being formed in the previous die.

During the intermittent movement of the die-holder to convey the blank in its "die opposite the plunger W and header M, or toward the completion of such movement, said plunger is moved forward, vto form a back or bottom to the die against which the blankis borne or pressed by the subsequent action of the header M, from the opposite side of the die-holder G.

After the plunger W has been thus adjusted, it remains stationary while the header M isfprojected forward, to form the rivet-head'on the end of the/blank.

Thev header M then retires, and the plunger Wsimultaneously moves farther forward through the die,

-to drive out the finished rivet, after which the plunger W retires, to allow of the die-holder G making its next movement. l

These-several and relative motions of the plunger W and header M are produced as follows :y

The header M has its necessary intermittent forward and back movements given to it, the first by a ca m, N, on the shaft B, acting against a sliding yoke or frame, 0, carrying the header, and the second by a cam, l?, acting against a back projection, Q, on said slidingframe. A

The plunger W is carried and made adjustable by frictional t or screwthread on it, through an arm, R, to adjust the working length or action of said punch to suit dierent lengths of rivets or bolts.

This arm R is carried by a rod arranged to project from or forming part of a sliding yoke, S, which is tirst moved intermittently in the one direction, to give to the plunger W its hereinbefore described two forward movements, by a swell, d', and toe-like projection e on a cam, T, acting in succession against a projection, on the frame S.

- by a cam,

The retiring movement of the plungerW is effected acting against a projection, V, on said sliding yoke or frame S..

-Both cams T and U are arranged on the shaft B. -By this machine work of' different lengths, but of the same diameter, can be made with the same dies and headers, by simply running the plunger W in 'or ont through the arm R, and changing or adjusting the gauge H to suit short-er or longer cuts.

The die-holder retainer K also insures great accuracy and steadiness in the working of the machine, and

the combination `and arrangement of the working parts generally efects a most perfect operation of the machine.,

What shere claimed, and desired to be secured by Letters Patent, is

The combination of the plunger W, operating in the twofoldcapacity ofvan anvil or supporter for and discharger of the blank, with the header M the mechanism to cause the plunger to advance and expel the blank simultaneously with the withdrawal ot' the header, and the series of dies in the intermittentlyrotating die-holder G, substantially as described.
